"Specification of Letters Patent. Patented June 29, 1915.

Continuation of application Serial No. 878,20 fi ed December 21, 1914. This app ication filed January 18,

To clljwh om itmay concern Be it known that I ys'rnrnnu D. 'LAYMAN,

a citizen of the United States, and a resident of Newark, county of Essex, and State of New Jersey, have invented certain new and] usefulImprovements in Hinged Lasts, of Which the following is a specification.

My invention relates to hinged lasts for use in the manufacture of shoes. and other among the objects of the present invention is to provide means for facilitating the assembly of hinged connecting means as described in mysaid former applicatiomand the provision 'ofmeans for imparting additional rigidity to Ilasts equipped with hinged connecting means constructed 1n accordance with my said former application. Other objects of my invention will appear in connectionv with its further description, and with the foregoing and related objects in view, my invention consists in the parts, improvements and combinations herein set forth and claimed.

In the accompanying drawing forming a partof this specification, and wherein the same reference numerals are uniformly applied to designate the same parts through out, Figure 1" is a side. view of a last embodying the present invention. Fig. 2 is a cross-sectional view thereof taken on the line 2-2, Fig. 1. Figs: 3 and 4: are side views, respectively, of the connecting'di'sks,

and Fig. '5 is a fragmentary cross-sectional view similar to a-portion of Fig. 2, but showing a slightly modified construction.

Reference numeral 10 represents the toe or forward part of the last and 11 designates the heel or rear part thereof. The rear. lower part 12"of theportion 10 of the last.

cated at 1 1 and 15, respectively, to make. room for the turning of the two parts of'the last relative to one another. 1 The provision made for receiving the rotary:- connecting 1915. Serial No. 2,823.

means comprises a transverse bore 16 extending transversely through the last at the center of rotation of the two parts 10 and 11 and formed part in each thereof, and a longitudinally extending recess made up of the partial recesses 17 and 18 also formed in the parts 10 and 11 of the last respec-' tively. The disks 19 and20 are received within the recesses 17 and 18 and preferablyfit fairly close therein, as shown in Fig. 2. These disks are arranged side by side as shown in Fig. 2, and soarranged are received within the recesses 17 and 18 in the two parts of the last.

In the form shown the disk 19 is secured to the forward portion 10 of the last to turn therewith, being provided with two holes 21 and 22 through which the pins 23 j and 2a, are passed, which pins also pass through the openings 25 and 26 provided 1n the portion 10 of the last for the recep-- tion thereof, andthe disk 19 is thereby rigidly held in the part 10 of the last and so that it can have no turning movement in relation thereto. The pins 23 and 2 1 also pass respectively through the slots 27 and 28 in the disk 20, said slots being of substantially the same length and being formed concentrically with respect. to the circular periphery of the ,disk. WVhile such disks are preferably circular in general outline, this particular form is not essential, so long as the holes and slots are con- .centrically arranged.

With the arrangement so describedit will be apparent that whereasvthe disk 19 is fixed with respect to the member 10 of the last, the disk 20 can rotate with respect thereto throughout the extent defined by the slots 27 and 28.

'On the opposite sides of the disks 19 and 20 p the reverse re'lation is had, the disk 20 being provided with holes 29 and 30 through which pass pins extending transversely through openings 31 and 32 provided therefor in the rear member-.11, such pins also passing through the slots 33 and34 in the disk 19. The disk 20 'is thus fixed so that it is prevented from rotating with, respect to the member '11, whereasthe disk 19 and the member- 10 secured thereto may rotate with respect to the portion 11 of the last, the disk 19 rotating with respect to the centric slots 33 and 34: in the disk 19. The

ice

member 11 to. the extent defined by the coni of substantially the same extent, and the holes 21, 22, 29 and being placed an equal distance from the center of rotation, it will be seen that by this. construction a rotatable connecting means is provided between, the parts 10 and 11 of the last, and

that such connecting means extends over a conslderable surface, and the four pins which secure the connecting means to thelast members being arranged ina circle, the entire connecting means turns thereon as upon a pivot of very-large diameter. 7

Any convenient arrangement of spring means fornormally holding the portions 10 and 11 of the last so that the parts 12 and 13 abut may be used; In the form shown the member'20secured to the rear portion 11 of the last is provided with an upstanding part having a forwardly projecting lug 36 which is received within theopening in the coil spring 37, said spring 37 entering a recess'38 provided therefor in the forward last member 10. Other constructions serving the same purpose may be madeuse of if rectiom As such preliminary assembling desired, certain alternative forms of construction for this and related purposes being shown and described in my said former application Serial No. 878,206, any one of which or others may be made use of in con nection with the device of'the cation.-

When the disks 19 and 20 are separated and no means of preliminary connection therebetween' is provided, as wa's the case in present applimy saidprior application, more or less difii' culty is encountered in assembling the same and 1n securing the pins, which secure the same,- in the holes 25, 26, 31 and 32 and the parts 10 and, 11 of'the last respectively.

A structure accordance with thepr'es ent invention obviates all difiiculties of this sort and at the same time serves to give the last added rigidity in a side to side diholes 39' and140 and a pin'41 is passed there through and means are provided on such pin for holding the disks 19 and 20 together and preferably fitting fairly closely within the transverse bore 16 so as to give additional side to side rigidity. Such result may be secured by the provision of sleeves 42", 42, one on the pin 41 on each side of the di'sks--19*and"20, which pin may be headed over, as at 43,43, or other constructions maybe resorted to for obtaining a similar result as, for example, a pin 44 may be pro vided' having an integral enlargement 45- on one end thereof and a sleeve 46 on the opposite end, the pin being headed over beyond the sleeve 46, as shown at 47, Fig. 5 Other forms of constructions may be resorted to for this purpose so long as the same pass centrally throughthe disks 19 and 20 and fit fairly closely within the transverse bore 16.

It will be seen tartan device 5011-. structed as above set forth the assembly of the parts is considerably; facilitated and at the same'time a more rigid and substantial structure may be secured. Furthermore,

while the centerof rotation is definitelyde fined by the disk,;pin, slot and hole construction at points away from the center of rotation, the provision of ithe pin passing through the central openings in the disk serves to aslight extent at least in securing a smooth and even pivoting action between the disksand the parts of the last to which they aresecured. While the pin preferably fits fairly closely within the openings 39 and 40 in the disks, this is. not essential as an extended pivotal mounting is provided forthe disks on the pins which secure the disks to the last portions, and the fit of the pin inthe holes 39 and 40 may be extremely loose so far as thepivoting action is concerned. Theside to side rigidity-of the Whole structure is, of course, improvedby giving'the' pin 41 or 44 a fairly closefit in the openings 89and40.

It is to be understood that the construction illustrated is only for. the purposeof afford- "ing a clear disclosure of my invention andmaking it readily understood, and that the invention is notlimited to such specific construction except as set out in my claims, and

that various modifications in anddepartures from such precise construction may be made, within the scope of myclaims, and without departing frommy invention or sacrificing any of-itsadvantages.

Having. thus described my invention, I

claim 1. In a last, heel andtoe portions, a' pair ofdisks set side'by side therein,'means for' securing one of said disks rigidly to. one of the last portions and rotatively to the-other of said last portions, means-for securing the other disk rigidly to the first named last 1 portion and rotatively to the other ofsaid last portions, and. means for rotatively connecting the disks at substantially the centers thereof, substantially-as setiforth.
